It is located on starboard side near the cap and rotor. Looks very similar to vehicle obd but has 2 rows of 5. Total of 10.
I’ve read the obd for mercruiser is on port side and has 4 or 5 pins?
just bought the boat and was attempting to conplete oil change but could not. I have the hull through oil drain but no oil came out however I was on slight hill and not was leaning towards drivers side. Is the oil pan drain on passenger side?
